Activity.Canceling Activity.Canceling Activity.Canceling Activity.Canceling Event


Occurs when the activity execution is canceled.

 event EventHandler<System::Workflow::ComponentModel::ActivityExecutionStatusChangedEventArgs ^> ^ Canceling;
public event EventHandler<System.Workflow.ComponentModel.ActivityExecutionStatusChangedEventArgs> Canceling;
member this.Canceling : EventHandler<System.Workflow.ComponentModel.ActivityExecutionStatusChangedEventArgs> 
Public Custom Event Canceling As EventHandler(Of ActivityExecutionStatusChangedEventArgs) 


Raising an event invokes the event handler through a delegate.

The Cancel method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

For more information about handling events, see Handling and raising events.

Notes to Inheritors

When overriding Canceling in a derived class, make sure to call the base class Cancel(ActivityExecutionContext) method so that registered delegates receive the event.
